SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

Limnologica publishes peer-reviewed articles addressing biological, physical and chemical aspects of freshwater ecosystems and adjacent habitats. We particularly invite contributions dealing with applied topics (e.g. ecotechnology, bioindication, restoration and conservation) and with less frequently investigated aquatic ecosystems and world regions such as South America, Africa and Asia).
Limnologica is a primary journal for limnologists, aquatic ecologists, freshwater biologists, restoration ecologists and ecotoxicologists working with freshwater habitats.
